RESPONSE OF MUNGBEAN TO FERTILIZER AND WEED MANAGEMENT

Abstract

A field experiment was conducted at Sher-e-Bangla Agricultural University, Dhaka during the period from March to June 2021 in Kharif-I season, to study the response of mungbean to fertilizer and weed managements. The experiment consisted of two factors, and followed split plot design with three replications.The experimental treatments with their levels were Factor A: different fertilizer managements with 3 levels (viz; F 1 = recommended dose (RD), F 2 = RD + 1 % urea foliar spray at flowering, F 3 = RD + 2 % urea foliar spray at flowering) and Factor B: different weed managements with 4 levels( viz; W 0 and 35 DAS, W 2 = No weed control, W 1 = Release 9EC spray at 30 DAS and W 3 ii = 2 hand weeding at 15 = Release 9EC spray at 20 and 40 DAS).The experimental results revealed that different fertilizer and weed managements significantly influenced the yield and yield contributing parameters of mungbean. Application of recommended dose of fertilizer along with 2 % urea foliar spray at flowering (F 3 ) influenced plant to have greater growth and yield of mungbean. The highest pods plant -1 (16.98), pod length (7.55 cm), seeds pod -1 (10.71), 1000-seed weight (37.16 g) and seed yield (961.50 kg ha -1 ) were recorded in F 3 (RD + 2 % urea foliar spray at flowering) treated plot. In case of different weed management, the seed yield ranges between (799.2-1022.4 kg ha -1 ). The highest seed yield (1022.4 kg ha ) was recorded in W 1 (2 hand weeding at 15 and 35 DAS) treated plot. In the case of combined effect of treatments application of RD + 2 % urea foliar spray at flowering stage along with 2 hand weeding at 15 and 35 DAS (F 3 W 1 ) influenced plant growth and development and recorded the highest seed yield (1159.0 kg ha ) while the lowest seed yield (575.0 kg ha -1 ) was recorded in the recommended dose of fertilizer with no weed control treatment (F 1 W 0 )
